Title: Patterns of association and distribution of estuarine-resident common bottlenose dolphins (Tursiops truncatus) with photographs and environmental parameters in North Carolina, USA from 2018-01-08 to 2018-01-26 (NCEI Accession 0254384)
Abstract: The NOAA Southeast Fisheries Science Center conducted surveys within the southern North Carolina estuarine system from 2018-01-08 to 2018-01-26 to provide an updated estimate of abundance for the Southern North Carolina Estuarine System Stock (SNCESS) of common bottlenose dolphins (Tursiops truncatus) using photographic-identification capture-mark-recapture (photo-ID) techniques. The surveys were strategically planned for winter when little overlap in distribution with the Northern North Carolina Estuarine System Stock (NNCESS) or coastal migratory stocks of bottlenose dolphins was expected. Because the sighting histories of individual dolphins have been an important tool for identifying or confirming stock membership, we also compared dolphins that were photo-identified during the 2018 surveys to dolphins that were included in a long-term photo-ID catalog dating back to 1995-07-10. Using the 2018 photographs and the long-term photo-ID catalog, we also evaluated the use of differences in Xenobalanus globicipitis infestation captured in photographs among individuals and groups as support for stock definition. This dataset contains the spatiotemporal sighting histories, photographs, observations of Xenobalanus globicipitis presence/absence, and environmental data for common bottlenose dolphin groups observed during the 2018 surveys. Data for individual dolphins observed during the 2018 surveys that were previously included in the long-term photo-ID catalog were provided as a subset with corresponding photographic matches. The sighting history and photographs of individuals matching from the long-term catalog are included with the exception of those dates indicated as capture events, as such photographs were not digitized.
